[Three rain valve to recommend Star Products - Mechanical seal] Description: interior, inner flow, the structure of the stationary type unbalanced mechanical seal, mechanical seal, medium temperature -183 ℃, additional pads with metal bellows (5) (3) instead of the general type seal rings to prevent leakage axial leakage and static ring (2) with the carrier ring (4) between the (element 4 when the material is suitable as a friction ring, the leak can be avoided) . Since both ends welded bellows, south pump TD40-25 / 2 machine seal, axial does not leak and no friction on the shaft. Under ultra-low temperature conditions commonly copper alloy or stainless steel bellows, compensation can maintain good flexibility and adaptation to mechanical vibration. Bellows in static state bellows reduce fatigue damage, extended pot life. [Three rain valve to recommend Star Products - Mechanical seal] Introduction: In the cooling mode, is the seal chamber and seal liquid tank conduit communicating with a closed-loop, south pump TD40-30 / 2 machine seal, the seal fluid in the reservoir tank after the finned air cooling and heat sealing liquid seal chamber temperature difference convection cycle. In addition, the sealed box enclosure distribute hot air in the inner diameter of the shaft of the fan base agitation, convection, reducing the sealed box sealed fluid temperature. The benefits of these two cooling methods that do not need cooling water consumption and external power source, low investment, low recurrent costs. Southern Pump TD40-20 / 2 mechanical seal, mechanical seal, mechanical seals, rain Wholesale (view) provided by Valve Co., Ltd. Tianjin three rain. Tianjin three rain Valve Co., Ltd. (www.tjsymf.com) (www.tjsymf.com) is a professional "mechanical seals, mechanical seal, shaft seal, mechanical seals, seals," the company. Since its inception, we adhere to the "good faith, sound management" approach, the courage to participate in healthy competition in the market, so that the "three rain" brand has a good reputation. We adhere to the "service first, customer first" principle, so that the three rain valve won the trust of customers in the public seal, and establish a good corporate image.
